STOP FOR ROLLER HAT'-'S|Z|NG MACHINES.

SPECIFICATION forming part of Letters Patent No. 243,189, dated June 21, 1881.

Application filed May 19, 1881.

To all whom it may concern:

Be it known that I, GEORGE YULE, a citizen of the United States, residing in the city of Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Stops for Roller Hat-Sizin g Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

My invention relates to an improved means of adj usting the swing-frame employed in roller sizing-machines to adjust the relation of the upper to the lower rollers; and it consists in means for connecting and operating simultaneously the stops commonly provided at both sides of the machine to check the descent of the swing-frame.

Figure l of the drawings is a side view of a three-roller machine fitted with my device, as shown in Fig. 2, which is a front view of two wedge-shaped stops mounted upon the front edge of the swing-frame, with a portion of the stationary frame A. Fig. 3 is a similar front view of two screw-stops similarly mounted, and connected by a shaft and bevel-gears.

A A is the main frame of the machine; 13 B, the -felting-rollers, which may be three or four in number as preferred.

0 O is the swing-frame hinged to the main frame A at O, and adapted to move the upper felting roller or rollers to or from the lower ones under the combined action of the treadle and the weight of the frame. The operation of the frame and rollers being well known ,no further description of the treadle is required.

D is the plank, and E the tank for wetting the felts.

ff are the stationary stops or cushions, preferably made of india-rubber or yielding material, and shown herein as applied to the two sides of the main frame A beneath the front corners of the swing-frame C. At each of such corners is shown, in Fig. 2, a wedge, a, arranged to slidelaterally, and being connected by a tierod, 1), any means applied to move one of them will necessarily move the other, and bring correspondingparts of the. two wedges into contact with the fixed stops f f when the frame 0 is lowered. Such an arrangement secures an equal adj ustment of both stops simultaneously, whereas by the devices heretofore used the 0p- (No model.)

erator was compelled to move each one separately, and was liable to set them unequally to the detriment of the felts placed between the rollers.

To move the wedges readily I form each one with a slot, to, and mount it upon a bolt, a, secured in a lug, 1, upon the front edge of the frame 0, and provide a pawl, cl, upon the tiebar I) and a rack, c, to fit it upon the front flan ge of the frame 0. A handle, (1, is attached to the pawl, and lugs d are provided upon the bar I) to carry the pawl in such a manner that the pawl can be lifted out of the rack and dropped into it again when the bar and its attached wedges have been moved into the required position.

The device shown in Fig. 3 consistsin a screwstop, h h, provided ateach corner of the frame 0, and having a head,p, to bear upon the cushion f. Lugsmand m at the corner of theframe embrace a bevel-gear, i, which is formed with a screw-thread in its middle, and the stop h is passed through it and through smooth holes in the lugs. The screws 7b are kept from turning by a key in the lug m fitting into a groove, 0, in the screw, and the stop is therefore raised and lowered when the gear is revolved between the lugs.

To turn the gears simultaneously a shaft, j, is'mounted in standards a n formed upon the front of the frame 0, between the gears, and similar cog-wheels at each end of the shaft, and a hand-wheel, k, in its middle afford the required means for moving both wheels and screws at once.-

By either of the devices described above the stops may be set exactly as desired in a few moments when the frame 0 is raised by the treadle but it is obvious that the adjustable stops in a-y be similarly operated by other means, and I do not therefore limit myself to the precise construction shown. The wedges a a may, for instance, have their angles opposed and be moved in opposite directions by aright and left hand screw, or a screw may be used instead of the rack c and pawl (Z for setting the tie-bar b, as desired. Bell-cranks may also be connected by a jointed tie-bar, as b, and be arranged to have their two horizontal arms bear upon the cushions f when they are set in position by the moving of the bar. The wedges may also both be made with an inclined face, as shown at the left side of Fig. 2, or with steps adapted to rest firmly upon the fixed stop, as shown at the right hand. The yielding cushion may also be attached to eitherthe fixed or movable stop, as preferred, and the adjustable stops may both be secured upon the frame A and moved simultaneously, as herein described, and the fixed stops ffbe placed opposite them upon the hinged frame 0, if desired.

Having thus fully described the nature and object of my invention, I claim the same in the following manner:

1. The combination, with the fixed and m ovable frames of a roller hat-sizing machine of the class herein described, of a movable stop applied to each side of the frames for adjusting the distance of the rollers, and means for moving them simultaneously, substantially as and for the purpose set forth.

2. The combination, with the frames A and C, of the wedges cut, rod I), rack 0, and pawl d, arranged and operated substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
